These core modules are not credit bearing. The dissertation is the only credit-bearing component of the programme. However, written assessment of a thorough understanding of the material recovered during these modules will be a requirement for proceeding with the programme. For the duration of the Doctoral Programme students will be required to attend and actively participate in a regular postgraduate seminar series, to present and discuss their work-in-progress with fellow students and their supervisors as well as for furthering dialogue on relevant sustainability issues and problems.
